Infineon Technologies has introduced its new XMC4000 32-bit microcontroller family, which uses the Cortex-M4 processor from ARM. The XMC4000 family supports three main trends in industrial applications: It helps to improve energy efficiency, supports a large number of communication standards and reduces software complexity during development. XMC stands for “Cross-Market Microcontroller” and means that, due to its configurability, the XMC4000 family is suitable for a wide range of industrial applications. Infineon is using this product to close the performance gap between the 16-bit XE166 family and the 32-bit TriCore family. The XMC4000 family is designed to enable scalable, compatible solutions with a high degree of software reusability. The XMC4000 portfolio consists of five series: XMC4100, XMC4200, XMC4400, XMC4500 and XMC4700. These series mainly differ in terms of core frequency, memory capacity and peripheral functions and number of I/O’s.
The XMC4000 family has a powerful CPU subsystem, DSP functionality, a floating point unit, a fast Flash memory with only 22ns read time and error correction code, large SRAM and extended peripheral functions. The extensive range of peripherals includes new timer modules, up to four parallel 12-bit A/D converters with a sampling rate of 70ns and a conversion time of 500ns, up to two 12-bit D/A converters, up to four high-resolution PWM channels integrated delta-sigma demodulator modules and touch button modules. Powerful communication is provided by an IEEE 1588-compatible Ethernet MAC, USB 2.0, CAN and SD/MMC interfaces and up to six serial communication channels which can be individually configured as UART, SPI, Quad SPI, IIC, IIS or LIN using software. In addition, the XMC4000 family offers a fast external bus interface that supports synchronous standards such as SDRAM or Burst Flash, and asynchronous standards such as SRAM, NAND Flash and NOR Flash. The integrated development environment DAVE 3 makes convenient, fast and application-oriented software development possible.
The first device in the 32-bit XMC4000 family that Infineon is bringing to market is the XMC4500 series. These microcontrollers offer a 120-MHz-CPU, up to 1 MByte of embedded Flash memory, 160 Kbytes of RAM and a comprehensive range of peripheral and interface functions. The peripherals include four parallel fast 12-bit A/D converter modules, two 12-bit D/A converters, four delta sigma demodulator modules, six capture/compare units (CCU4 and CCU8), two positioning interface modules, and a module for eight touch buttons. Communication functions comprise interfaces for Ethernet, USB, and SD/MMC. In addition, the XMC4000 family offers three CAN modules, six serial communication channels and one external bus interface for communication. The package options are LQFP-144, LQFP-100 and LFBGA-144.
